Title: Production of silicon single crystal
Inventor: HAGA HIROTSUGU
IPC: C30B15/00
Filed: 1992-05-25
Abstract: PURPOSE:To improve the quality by forming an Si ingot having a necked tail composed of a neck part which is the middle of the tail converging from the terminal end of a straight drum part into a conical form, a conical part following the neck part and the rear end part and treating the resultant ingot at a specific temperature. CONSTITUTION:A neck part is formed into >=10mm diameter and a conical part is formed into a diameter of >= (neck part diameter + 8mm) so as to prevent an Si ingot from falling off during the heat treatment at a high temperature. The dislocation is caused by plastic deformation with the resistance supporting the ingot weight by the neck part 3 and the conical part 4 during the heat treatment. The diameter of the neck part is regulated to <=1/5 that of the straight drum part so as to prevent the dislocation from propagating to the interior of the straight drum part 1. Furthermore, the conical angle (alpha) of the conical tail 2 is regulated to an acuter angle than 90 deg.C so as to make the propagation region of the dislocation stay in the conical tail 2. The Si ingot of this shape is then held with a suspending jig of a heat-treating furnace, nearly vertically hung and heat-treated at 1150-1400 deg.C. After completing the heat treatment, the ingot is cooled to <=1150 deg.C in the furnace and then taken out of the furnace to afford the objective Si single crystal without containing crystal defects.

Title: Control device for solenoid valve
Inventor: TAKASAKI HIROSHI
IPC: F16K31/06
Filed: 1987-05-29
Abstract: PURPOSE:To aim at saving electric power by allowing an oscillating circuit to carry out the switching operation of an exciting circuit after the time of a timer elapses so that the level of current for a solenoid coil is lowered substantially to the level of a holding current, and by using regenerative current. CONSTITUTION:During initial stage in which a power source 1 is turned on, the charged voltage of a capacitor C3 in a timer circuit 7 is low so that a transistor Tr3 is turned off, and accordingly, an exciting circuit 4 feeds current to a solenoid coil 3. Next, when the charge voltage of the timer circuit 7 reaches a predetermined value, a constant voltage circuit 8 and an oscillating circuit 6 allow a switch circuit 5 to perform switching operation at an oscillating frequency which is less than the time constant of the solenoid coil 3 determined by the time constant of C2, R14 and R15, and the exciting circuit 4 carries out the turn-on and -off control of current for the solenoid coil 3 so as to lower the level of current down to a low level of a holding current. Further, a counter- electromotive force regenerating circuit 9 regenerates flywheel current for the solenoid coil 3 by use of reverse voltage produced during turn-off operation under turn-on and -off control. Thus, it is possible to aim at saving electric power for the solenoid valve.
